What a great trip - I think I have discovered your route...
changed the oil and lubed the suspension ( for starters ) prepping for a 10K TRIP TO Seattle in mid June. Tom Taylor COG#7173
Also finished backs using Duplicolor truck bed liner spray and covered in saten black.Replaced all clutch/brake fluids. Pic shown is what I found....
Cleaned it but good!! Broke out the Pledge and went at it till I could see myself.
I replaced the actuator cable that runs from cruise servo to the throttle linkage. It was down to one strand.
